Services listed in Task Manager

November 2, 2012 at 11:36:06
Specs: Win 7
Windows 7 Home Premium 64-bit, with SP-1.

With no programs running, I find 136 services listed in Windows
Task Manager. Although more than half of them are stopped,
many of them shouldn't be in the list at all, because I disabled
them in services.msc. For example, bitlocker and bluetooth.
Why do these still show up in Task Manager?

The Task Manager services tab shows all services, including those that are disabled or not running for some other reason. This is by design.

Be very careful when disabling system services. Many do more than is shown and may cause unpredictable behavior if disabled. Inactive services take very little resources so disabling them will do next to nothing for performance.

My question, then, is: What do you mean by "all services"?

I expected that Task Manager would only know of services
that were loaded into memory. If that is wrong, where does
it get its list of services from?

There is a list of all installed services in the registry and Task Manager obtains the list from there via the system functions. The details of how it does this are not documented.

Task Manager on my Windows 7 installation shows all services, including those that are disabled. This is the way it was designed to work.
